[amibroker] Backtesting Forex

OK, perhaps someone can help us out here.
I'm try to simulate buying a fixed lot for each trade. i.e Retail forex generally trades in mini lots of $10k or normal lot of $100k.
I don't want my postion increased/decreased each trade as a percentage of the account. Just 1 fixed $10k lot per trade.
That would be approx $1 profit per 0.0001 (1 pip)
I've tried various combinations of PointValue, PositionSize, PositionSize = MarginDeposit = 1, NumContracts etc but results are still screwed. eg.


Ticker          Trade            Date                            Price Ex. date                            Ex. Price % chg   Profit  % Profit  Contracts  Position value Cum. Profit   # bars Profit/bar MAE MFE 
EUR A0-FX Long (profit) 24/03/2004 11:00:00 AM  1.22754 24/03/2004 11:15:00 AM 1.2291       0.13% 1.85    63.34%  119               2.92            1.85              2       0.93    .01% 0.13%


Hopefully the table wasn't screwed in the post.
But as can be seen Contracts = 119 where should be =  1 lot and profit isn't represented properly even though Ticksize= 0.0001 & Pointvalue = 1 i.e $1 In this case profit should be $16
And the contract size varies from say 119 to the very next trade being 6459. I don't quite understand what is happening.

Thanks for your time!
